Abstract
In rats hepatocellular cytoplasmic changes after daily repeated D-galactosamine (GalN) intoxication--i.e. subacute GalN intoxication--were studied by light and electron microscopy. The number of GalN injections--and thus the days of survival--was between one and 30. The rats were killed six hours after the last GalN injection. Less degenerative changes were found after repeated GalN injections. An increased formation of atypical dense bodies (ADB), a temporary pronounced lipid accumulation and changes of the rough and smooth endoplasmic reticulum were prominent features of subacute GalN intoxication. The implications with respect to a modified GalN action in subacute GalN intoxication are discussed with special reference to biochemical data obtained in the same experimental model (Schuchhardt et al., 1977).
